To all whom it may concern:

Be it known that I, ORLANDO SUMNER, a citizen of the United Kingdom of Great Britain and Ireland, and resident of The Cottage, Netherton Road, St. Margarets-on- Thames, Middlesex, England, have invented certain new and useful Improvements in Apparatus for Bleaching and for Preparing Bleaching, Deodorizing, and Disinfecting Solutions,'of which the following is a specification, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to apparatus for preparing bleaching solution and to that type of apparatus in which a salt solution is electrolyzed by the immersion therein of the positive and negative poles of a source of electricity' In this type of apparatus it is customary to separate the said poles, or as I ,willcall them the cathode and the anode, by a wall or partition and it is very advantageous "to circulate the solution around the anode and so construct the a paratus that the hydrogen evolved from t e cathode shall escape into the atmosphere with a miminum of damage, that is to say without mixing with or carrying with 1: much of the chlorin gas evolved at the anode, and the primary objects of my invent-ion are to automatically obtain these two results to a practically complete degree. I may, however, provide means whereby a controllable quantity cathode is permitted to pass through the said wall, and vice versa, because for some special purposes this intermingling may be advantageous.

In constructing my apparatus I may employ cathodes and anodes of any convenient shape, for example, I may adopt cathodes of the rod type and use anodes of plate type. These anodes and cathodes are supported upon bus bars or equivalents, or otherwise supported in any convenient manner.

A particular feature of my apparatus and that by which to a very large extent I obtain the above-mentioned advantageous features, namely the automatic circulation and the escape of the hydrogen without loss of chlorrn is that I arrange the cathode in a gompartment which ma be described as bemg conical or wedge-s aped in. cross secof solution from the "that chlorin gas evolved flow is shown by the small arrows,

tion, the wider end being said cathode being vert cal or set at any desired angle therein. I place the anode or anodes in suitable proximity to the outside walls of the com artment and preferably at such an angle From the perpendicular as will, owing to the chlorin gas rising from them, and as hereinafter described, promote the automatic circulation. The angle at which the anodes are set may advantal yv b Parallel to the outside sloping walls of the cathode chamber so that chlorin gas evolved from the anode, will, as to one side thereof rise upwardly between the said wall and the anode, and cause an n of the liquid in the passageforme by the wall and the anode, while that evolved from the 0V posite side of the anode will pass up uppermost and the stream wardy along same to the surface of the liquid.

An example of my invention is shown in the accompanying drawings, in which Figure 1 is a vertical section of an earthenware or other tank a in which my apparatus is placed, the said apparatus consisting of a tapered chamber b the walls of which may be of porous, say finely perforated vulcanite, or non-porous material, surrounding the cathode c, the anodes a? being arranged outside the chamber 1) on opposite sides and as will form the small passages e. The anodes d are shown connected to their bus bar by graphite studs (1' the higher ends ofthe anodes being below the level of liquid which can therefore flow over the top of them. The bottom of the chamber 7) has small, and if desired controllable openings f and is furnished at g with passages con trolled by taps hand having on the inside shields i so arranged that the gases evolved from the cathode rising upwardly within the said chamber are prevented from entering the said passage. It will be obvious from the anodes (Z on the side next the chamber 6 will pass along the passages e and in the particular construction shown will be deflected by the overhanging walls b. The direction of while the chlorin evolved on the outer side of the plates (2 will travel up the under surface of the plates as shown by the arrow heads.

in such proximity thereto g; y 1,075,873 v The flow of chlorin gas will cause the genoral circulation of liquid Which I indicate by the long arrows. Fig. 2 shows in plan an apparatus similar to that shown in Fig. 1.

Obviously two or more sets of my electrical apparatus may be arranged in the same tank and the latter may be of any convenient kind, and the anodes may be in one or more rows or groups.

What I claim and desire to secure by Letters Patent is:

1. Apparatus for preparing bleaching so lution comprising a tank, a tapered chamber within the tank, an opening from the tank to the chamber, an electrode in the tankand an electrode in the chamber.

2. An apparatus for preparing bleaching solution comprising a tank, atapered chamber within the tank, an electrode in the tank,

an electrode in the chamber and'passagesfor communication between the tank and the chamber.

3. Apparatus for preparing bleaching solution comprising a tank, a tapered chamber within the tank, an electrode in the tank, an electrode in the chamber and an opening at the bottom of the chamber.

4. Apparatus for preparing bleaching solution comprising a tank, a tapered chamber within the tank, electrodes in the tank and electrodes in the chamber, an opening at the bottom of the chamber and an opening toward the top of the chamber for the circulation of liquid through the tank and the chamber.

5. Apparatus foupreparing bleaching so lution comprising a tank, a tapered chamber within the tank, an electrode in the tank, an electrode in the chamber, passages for communication between the tank and the upper part of,;the chamber and an opening at the bottom of the chamber.

6. Apparatus for preparing bleaching solution comprising a tank, a tapered chamber within the tank, electrodes in the tank and electrodes in the chamber, the electrodes in the tank being set substantially parallel to the walls of the tapered chamber.

7. Apparatus for preparing bleaching solution comprising a tank, a tapered chamber within the tank, openings from the tank to the chamber, electrodes in the tank and electrodes in the chamber, the electrodes inthe tank being set substantially parallel to the walls of the chamber, and of a distance 9. Apparatus for preparing bleaching solution comprising a tank, a tapered chamber within the tank, an electrode in the tank, an electrode in the chamber, and controllable passages for communication between the tank to the chamber, shields being arranged over the passages Within the tapered chamber. 7 i v 10. Apparatus for preparing bleaching solution comprising a tank, a tapered chamber supported therein and thereby, electrodes in the tapered chamber and electrodes in the tank. v

11. Apparatus for preparing bleaching solution comprising a tank, a tapered chamber supported therei-nand thereby electrodes in the tapered chamber and electrodes in the tank, both said electrodes being also supported by the tank.

12. Apparatus for preparing bleaching solution comprising a tank, a tapered chamber within the tank, an electrode in the tank and 'an electrode in the chamber,'the electrode in the tank being set at such angle in relation to-the vertical-and at such position in relation to an outside wall of the chamber as will cause gases. emanating-from the electrode to produce circulation of liquid in the tank.

13. Apparatus for preparing bleaching solution comprising a tank, a tapered chamber within the tank, an electrode in the tank and'an' electrode in the chamber, the electrodes in the tank being set at such angles in relation to the vertical and at such positions in relation to outside walls of the chamber as will cause gases. emanating from the electrodes to produce circulation of liquid in the tank.

In witness whereof I have hereunto set my hand in presence of two witnesses.
